M4700B Marten scarer for 12 V =
vehicles with multi-contact high-voltage brushes
The M4700B marten scarer works in three ways: ultrasound, electric shocks via new multi-contact
brushes and pulsating light
The M4700 emits electric shocks via multi-contact fur brushes to the marten in the engine
compartment. Positive and negative brush legs are applied simultaneously, which sweep through
the marten‘s fur and emit strong electric shocks directly onto the marten‘s skin. In case of customary
plates it is necessary that the marten touches these with the snout or paws. The fur, however,
insulated and protected the animal. The brushes penetrate the fur now and enlarge the “surface of
attack” by a multiple. The high-voltage stainless steel brushes may be mounted in any place in the
engine compartment so that a flexible shielding, which is adjusted to the respective vehicle is
achieved.
In addition, the control device emits very strong, aggressively pulsating ultrasonic sound in a 360°
radius. This sound randomly varies in frequency and rhythm (so the marten cannot become
accustomed to it).
Due to the water tightness and the completely closed loudspeakers, the device may also be
mounted at deep positions and withstands motor washes, too.
The innovative voltage circuit automatically operates the device as soon as the engine is switched
off. The elaborate connection at terminal 15 is now no longer required. There is the simplest 2-pole
connection, which saves significant installation time.
